The Seattle Times reports that Jaden Griffin died on Thursday, according to the King County Medical Examiner's Office. Two days before, he had slipped on rocks and was pulled over the falls, a drop of about 30 feet.

He was recovered from the undertow about two hours later and initially reported as dead. But doctors said there might be a way to revive him because he'd been in cold water. They kept him on life support and took him to Seattle Children's Hospital.

The boy had been visiting the falls near Bellingham with his parents and a 5-year-old sibling. Police and hospital staff have not said where the family lives.
